If the game has a decrypted eboot.bin it will kick u back to the livearea you need a fully clean untouched iso for them to work or at least the eboot.bin and boot.bin have to not be decrypted.. This is something I found out thru various test with my dbz tag iso

Thank you Mrgreezy3 but please help me: I have an iso, how can I encrypt eboot.bin and boot.bin or how can I verify if they are encrypted? This tutorial just says to sign again the eboot.bin. Do I need to sign boot.bin too?
